data.bvec: 3D b-table Vectors for Data Acquisition
Description
3D grid file containing the sampling points used in diffusion data acquisition for file data.nii.gz.
Format
data.bvec is in ASCII format, specified as a sequence of values,
as produced by the 'dcm2nii' tool, and compatible with the formats used
in the 'DSI_Studio' and 'Dipy' toolboxes.Details
The file data.bvec has 203 points uniformly distributed on a 3D (DSI) grid limited to the volume of the unit sphere.
The data set data.nii.gz is NIfTI-converted from the DICOM data set provided by the Advanced Biomedical MRI Lab, National Taiwan University Hospital, under the designation DSI 203-point 3mm.
